To all whom it may concern:

`Be it known that I, GEORGE GHALLONER, ot'Omro,in the county ofWinnebago and State of ,Wisconsin, have invented a new and ImprovedjShingle-Machine.; and l do hereby declare that the following is a full,clear", and

exact description` thereof, which will enable thoseskilled in the art tomake and use the same, reference being had to the accompanying drawings,forming part of this specilication, in which- Figure 1,- SheetNo. 1, isaplan on top view of my invention; Figs. 2, 3, 4,and.5, enlarged sectionspertaining to the same; Fig. 6, Sheet No. 2, a vertical section of thesame, taken in thelinea' Fig. 7, adetached plan or togl 'view of the`circular saw and adjustable be pertaining to the same; FgfS, a sideviewof Fig. 7 Fig. 9, a transverse vertical section of Fig. 7, taken in theline y y; Figs. 10 and I1, detached views of the adjustable bedpertaining to the same. l

` Similar letters of reference indicate corresponding parts. l v Thisinvention relates to a new and improved ,machine for sawing shingles,and of that class in which a series of bolts are placed upon a thewheel.

' The object of the' invention is tofobtaina' shingle-machine of theclasssp'eciied which will operate with but little friction, perform itswork rapidly, and set the bolts automatically, so that the shingleswillbelcnt in proper taper form-q l a framing,which may beconworkingparts of the machine,and B is ashaft which has a vertical position inthe framing-A, and has ai horizontal wheel, C, upon it, braced rims, bb', attached to radial arms o', which project horizontally from theshaft B. `The two rims b `b' are connected by radial strips d, of taperform, placed. at suitable distances apart, the spaces between thestrips, owing tothe i taper form of the latter, being of Aequal widthgiroughout their entire length, as shown in The outer rim, b, is toothedat its outer edge,

The inner rim, V b,is of polygonal form, a straight side being at jthe inner end oi' each space between the 'strips j d, as shown-inFig. 1. Each of these spaces ,e t between the strips d is provided atits inner f end with a serrated jaw, F, having arod e projectinghorizontally from it, with spring, f,thereon. Thesesprings have ency tokeep the jawsl F pressed towa olter rim, b. 'The jaws F are connect rodsg to cranks It, which are at theupp'e of shafts fitting in bearings i atthe inne `of the rim b. The lower ends of these also have cranks j onthem, with roller their ends.

Gis a frame, which may beof segine t which a circular saw, E [Gisplaced,said saw j being at the top of the frame G anddirectly underneaththe rims b b'. j `In thisframeGrthere is also placed a tilting bed, I,which is fitted and forks freely on journals l L at theupper i them,said screw-rods passing through a plate, j i, i n, which has apendentbar, o, at each end of it, jfl

said bars o being connectedby pivots to arms p on a sliding shaft,`K,whichis adjusted by a 1 screw-and n nt, as shown clearly in Fig. 9. By il means of this sliding shaft K the plate n Inlay4 be raised-and loweredas-desired, and conse# quentlythebedI. j f

L represents a sliding bar,which isunderneath the bedI, and hasltwoinclined projee tions, g q, on which thebed 'Il rests. i This barL jL is allowed toslide or work freely in tbeup` per part of the frame G,and it is connectedat To one of the arms of the wheeltltherefisattached, by .a pivot, a pendent lever, N, which The bolts from whichthe shingles are sawed are fitted in the spaces betweenthe strips d, iand are clamped and held` inposition by the serrated jaws F, whichareacted upon by the i springs f., The bolts thusclampedpass,bytheV i yrotation ofthe wheel C, successively over the le saw H,which cuts ashingle from the lower` I The taper form 1s given the shingles by the.;inclination of the `bed I, on which the bolts drop just previous tocoming in contact with the saw. The jawsF are drawn back to release thebolts and permit them to drop on a platform, O, on the frame G, landthey are moved along on the platform to the bedl, andare then againclamped,- the jaws F being drawn back in consequence of the rollers kcoming in contact with a projection, t, at the inner side of the rim b,the rollers passing off from said projection just as they come in linewith the lied I, in order to allow the springs f to throw thcjaws F incontact with thebolts.

The bed Ifis tilted o'rinclined at every revolntion of the Wheel Chy)means ot' the lever N, attached to said wheel, the lever actuatin;rthe lever M on frame G, which lever M moves the sliding bnr L, theinclined projections q q of which move-or tilt the hed,`the latter beingtilted or inclined rst in one position and then iii-:the other, theinclination being'reverscd at every revolution of wheel C, so that theshin gles will be cnt in taper i'ornx.

' The saw-shaft B mayv be rotatcd'by. means I prei'er the offriction-wheels or gearing.

By constructing' the wheel C with bracerods a, as shown, I avoid the useof frictionrollers to support said wheel, and hence get rid of muchfriction.l t

Having thus described myinvention, I claim as new and desire to secureby Letters Patentl. The means employed for operating or tilting the bedI-to wit, the sliding bar L, provided with inclined projections q q, thelever M, attached to L, and the lever N', attached to wheel C, allarranged siibstantially as set forth.
